Breaking long blocks of text with images — a rule or a myth?

Question

I once heard that in web pages with long text blocks, one needs to break those blocks with illustrations, so that the potential reader isn't intimidated by the large amount of text. The rule, so I heard, is that even if you don't have any related illustrations, you should find *something*, as long as it breaks the text. Is this really a rule? Is there a technical term for such a behavior and where can I read more about it?
